My invention relates to the construction of cylinders such as are usedin washing and dyelng machines and has for itsob ect to prov1de a slmple, strong and economical construction for such cylinders.

Cylinders, such as I have in view, are constructed with end plates and ashell generally made up of sheet metal plates and are provided with radial partitions dividing the inner ends to the central shaft and at their outer ends to the tie rods and the other set of 'plates connected at their inner ends with the tie "rods and at their outer ends to the shells of the cylinder. This, .broadly speaking, is the leading feature of my invention and by preference I provide the centrally located shaft with a series of radial slots and the tie rods with diametrically oppositely located slots and. secure the inner set of partition plates in the slots of the shaft and tie rods and the outer set of partition plates I secure in the oppositely located slots of the tie rods at their inner ends and to the shell at their outer ends. r r Reference being now had to the drawings which illustrate constructions involving my invention Figurel is a cross sectional elevation of a cylinder constructed in accordance with the preferred form of my-invention. I Figure 2 is an enlarged sectional view of thecentral shaft and the ends of the partition 7 Figure 3 is an enlarged sectional view of oneof the tie rods and of the partition platessecured thereto.

Figure 4 is a sectional elevation of a modified form of my construction.

Figure 5 is a longitudinal sectional view of the construction shown in'Fig. 4:.

Figure 6 an enlarged sectional view of the central shaft and of the inner ends of the partition plates secured thereto.

the end I) the inner ends of the inner Figure. is an. enlarged sectional View of one of the tie rods showing the mold in'which the partitionplates are. secured thereto and ;Figure 8 is an enlarged sectionalview showinglthe preferred mode of attachment of the outer partition plates to the shell. I n

A, Figs. 1, 2 and 3, is a centrally located shaftbrrod extending between theend plates of the washing machine cylinder and formed,

asishown, with four radial slotsyindicated at At; A etc. B indicates the end plate of-the cylinder G,.C, etc. a series of tierods securing the end plates together at points aporoxi mately midway between the central shaft and the shell of the cylinder and formed with diar al y Opposite slots, as indicated at C RD, D, etc. area series of curvedmetal p inaking'upthe shell oftheacylinderpthese plates, as shown,beingprovidediwith hook theyare secured.

like joints D D which togetherfin -pairs, The other ends" of the plates, asis best shownin Fig. 8, are formed one with anoutwardly turned-flange D and" the other with afolded'over straight flange, indicated" at D These ends are secured together and to the ends of the partition plates H by means of an angle plate E, E and a U-shaped clip F, having a flange F between which and the portion E of the angle plate Bolts G secure the structure together. This joint is shown as a indicated, and not as forming a partof my present'invention, which permits of any desira'ble mode of attachment of the plates to gether and to the partition plates.

In the construction shown and 7, a indicates an unslotted centrally located shaft connecting the end plates B, B

and 0, 0, etc., a series ofunslotted tie rods also connect-mg the end plates and located approximateiy midway between the shaft and the shell of the cylinder. In this construction set of partition plates indicated at h are bent into eyes, as best shown at M, Fig. 6, these eyes extending around the shaft a and interengaging with each other, as shown in Fig. 6, the outer ends of the inner series of partition plates h and in Figs. 4,

of one of the plates is secured. 7

good one forthe purpose the inner ends of the outer series of partition plates h are also bent into eyes, as best shown in Fig. 7, these eyes partly surrounding the tie rods 0 and partly around each other, as shown, the outer ends of the outer series of partition plates being secured to the shell, as

indicated in Fig. 8.

It will be seen that in either of the two described constructions a simple, strong and in,- 30 expensive structure is provided for Which permits comparatively light partition plates to be used and at the same time provides a strong partition capable of resisting all the strains to which such partitions are-subjected.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A washing machine cylinder having end plates and a cylindrical shell, the combination 1 therewith of a central longitudinal shaft, a

series of parallel tie rods connecting the end plates and located between the shaft and the shell, a series of partition plates attached at their inner sides to the central shaft and at a their outer sides to one of the tie rods and a second series of partition plates attached 'at theirinner sides to a tie rod and at their outer sides to the shell.

2. A washing machine cylinder having in combination a central radially slotted shaft, as'eries of stay rods located between said shaft and the shell of the cylinder in radial alignment with the slotsof the shaft, said stay rods having diametrically oppositely located slots 2. formed in them, a series of partition platesheld in slots of the shaft and oppositely located slots in the stay rods and a second series of ipartitionplates secured at one side in the outer slot of the stay rods and at their other a sides to the shell of the cylinder.
